【考案の詳細な説明】
本考案は永久磁石にむける磁極部の磁束密度を変化させ
てドアーを開閉することを特徴とするドアーのロック機
構に関するものである。[Detailed Description of the Invention] The present invention relates to a door locking mechanism that opens and closes the door by changing the magnetic flux density of the magnetic pole toward the permanent magnet.
本考案の目的は、至極簡単な構造によりロック作用が確
実に行われ、しかも開放動作が非常に軽い力で行われる
ドアーのロック機構を提供することにある。An object of the present invention is to provide a door locking mechanism that has an extremely simple structure, ensures a locking action, and allows an opening operation to be performed with a very light force.
前記の目的を充足するため本考案は次のように構成した
ものである。In order to satisfy the above object, the present invention is constructed as follows.
即ち、本考案は非磁性体１と強磁性体２とから成る一対
の板状主体３を空隙４を存してドアーＤに内装し、前記
強磁性体１をドアーＤの内面側に位置させ、かつ把手５
を有する永久磁石片６を前記空隙４内に摺動可能に収容
して永久磁石片６のストッパー７を設け、把手５をドア
ーＤの外部に露出させ、更にドアーＤを蝶着した本体に
の表面に前記永久磁石片６と強磁性体２に吸着される強
磁性部８を設けたドアーのロック機構である。That is, in the present invention, a pair of plate-shaped main bodies 3 made of a non-magnetic material 1 and a ferromagnetic material 2 are housed in a door D with a gap 4 therebetween, and the ferromagnetic material 1 is positioned on the inner surface side of the door D. , and handle 5
A permanent magnet piece 6 having a diameter is slidably housed in the gap 4, a stopper 7 is provided for the permanent magnet piece 6, the handle 5 is exposed to the outside of the door D, and the door D is attached to the hinged body. This is a door locking mechanism in which a ferromagnetic part 8 that is attracted to the permanent magnet piece 6 and the ferromagnetic body 2 is provided on the surface.
尚図示実施例では強磁性体２で成形したコ形板状主体３
の中間を切り落してその間に非磁性体１を介装しその前
後に強磁性体２及び２′を位置させたものを示す。In the illustrated embodiment, a U-shaped plate-shaped main body 3 made of a ferromagnetic material 2 is used.
A non-magnetic material 1 is interposed between the two, and ferromagnetic materials 2 and 2' are placed before and after the non-magnetic material 1.
そして］形枠状の正面のストッパー７．７間に把手５の
突出孔９を開設する。] A protrusion hole 9 for the handle 5 is opened between the frame-shaped front stoppers 7 and 7.
１０は把手５と永久磁石片６間の非磁性体材料を用いた
連絡片、１１は永久磁石片６に作用させた復帰はね、１
２はドアー〇内面に囲繞したバンキングを示す。10 is a connecting piece made of non-magnetic material between the handle 5 and the permanent magnet piece 6; 11 is a return spring acting on the permanent magnet piece 6; 1
2 shows the banking enclosed on the inner surface of the door.
又永久磁石片６のＮ、Ｓ極は第４図に示すように表裏両
面に表われる。Further, the N and S poles of the permanent magnet piece 6 appear on both the front and back sides as shown in FIG.
本考案は以上の構成であるから、先ずドアーを開く過程
では、把手を引張ると、永久磁石片６は摺動して非磁性
体１１！！に移る。Since the present invention has the above-described structure, first, in the process of opening the door, when the handle is pulled, the permanent magnet piece 6 slides and the non-magnetic material 11! ! Move to.
ゆえに吸着部に近い強磁性体２と永久磁石片６によって
つくられる吸着部の磁力は減少して殆んど零になったと
きにドアーは静かに開かれる。Therefore, when the magnetic force of the attraction part created by the ferromagnetic material 2 and the permanent magnet piece 6 near the attraction part decreases to almost zero, the door is opened quietly.
次に閉じる過程では把手を押すと、ドアー及び永久磁石
片は前進して強磁性体側に移動する。Next, in the closing process, when the handle is pushed, the door and the permanent magnet piece move forward toward the ferromagnetic material.
従って吸着し易くなり、強くドアーを押せば最も強い吸
着状態で本体側の強磁性部８に強力に吸着する。Therefore, it becomes easier to attract, and if you push the door strongly, it will be strongly attracted to the ferromagnetic part 8 on the main body side in the strongest attraction state.
かくして本考案のロック機構を例えば図示実施例のよう
に冷蔵庫に実施した場合、中空ゴムバッキング１２の圧
潰作用は均等に、強く行われるので、従来のように全周
にフェライトを囲繞させる無駄を省くことができる。Thus, when the locking mechanism of the present invention is implemented in a refrigerator as in the illustrated embodiment, the crushing action of the hollow rubber backing 12 is performed evenly and strongly, thereby eliminating the waste of surrounding the ferrite all around as in the conventional method. be able to.
要するに本考案によればドアーは強力に本体側に密着さ
れ、殊に開放閉止動作が円滑に軽くできる効果を奏し、
ドアーのロック機構として優れた考案である。In short, according to the present invention, the door is firmly attached to the main body, and the opening and closing operations are particularly smooth and light.
This is an excellent idea for a door locking mechanism.
尚］形の板状主体３は図示実施例のように非磁性体１を
強磁性体２，２′の間に介在させず先端側に強磁性体２
を後端側に非磁性体１とした２分割の形状でも差支えな
い。Note that the plate-shaped main body 3 of the shape does not have a non-magnetic material 1 interposed between the ferromagnetic materials 2 and 2' as in the illustrated embodiment, but has a ferromagnetic material 2 on the tip side.
A two-part shape with non-magnetic material 1 on the rear end side may also be used.
